Along with our Juncoes, a perky winter sparrow around here in the Northeast US.
As weather warms up (not yet) they have a very sweet call before they depart to breed in the coniferous parts of Canada.
A similar bird, the White-Crowned Sparrow, is rarely seen here because they migrate from their breeding gounds on the tundra to winter further south. They do not seem to stop by for a rest.
